Advice on a new set of ear muffs

Hey Guys.

Its been about 4 years since i purchased my Walker Razor ear muffs and they are starting to not work as much as they used to. Im in the market for some near ear muffs.

I mainly shoot pistols but occasionally rifles. What would the experts here recommend?

Thinking my budget could be up to about $300 AUD.

Keen to hear your thoughts.

Thanks in advance
